"No, not nervous," Ajayi said of his debut. "I'm confident in my talent and ability. It's just about, like I said, whenever I got my chance, just making sure that I took full advantage of it."

Elsewhere, quarterback Dak Prescott completed 21 of 33 passed for 249 yards and two touchdowns to lead the Dallas Cowboys to a 28-17 win over the Kansas City Chiefs.

"Seeming him every week, he's someone that can beat you a lot of different ways," Dallas head coach Jason Garrett said. "He makes plays in the pocket and he make plays out of the pocket. He makes plays with his feet. He did that all throughout this ball game."

The Cowboys improved to 5-3 on the season thanks to the trio of Prescott and wide receivers Terrance Williams and Cole Beasley who proved to be an unstoppable force against the Chiefs.
